Description

Technical Field

[0001] This utility model relates to the field of server rack technology, and more specifically, to a server rack internal environment temperature control device. Background Technology

[0002] A server rack is a freestanding or self-supporting enclosure used to house electrical or electronic equipment. It is an indispensable component of electrical equipment and serves as a carrier for electrical control devices. Server racks are generally made of cold-rolled steel or alloys and are categorized into server racks, network racks, and control racks. The electrical equipment inside the rack generates heat during operation. Existing rack cooling structures are relatively simple, typically relying only on fans and vents for heat dissipation, making it difficult to expel heat effectively. This leads to excessively high internal temperatures, increasing the risk of damage to the internal electrical equipment. Therefore, this invention designs a rack internal temperature control device to address these problems. Utility Model Content

[0003] The purpose of this invention is to provide a cabinet internal ambient temperature control device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A cabinet internal ambient temperature control device includes a cabinet with a hinged door on the front side. Two air inlets are symmetrically arranged on the top of the cabinet, each with a guide shroud. A blower fan is fixedly installed inside the guide shroud. Several left air outlets are spaced apart on the left side of the cabinet, and a heat-absorbing bend I is installed inside the cabinet near the left air outlet. Several right air outlets are spaced apart on the right side of the cabinet, and a heat-absorbing bend II is installed inside the cabinet near the right air outlet. A U-shaped heat-absorbing tube is fixedly connected between heat-absorbing bend I and heat-absorbing bend II. Several heat-absorbing rings are fixedly sleeved on the outside of the U-shaped heat-absorbing tube at intervals. A temperature sensor is installed on the inner wall of the cabinet. A cold water tank is fixedly installed on the back side of the cabinet by a bracket. A water pump is installed on the cold water tank. A water pump inlet port is fixedly connected to a water pumping pipe extending into the cold water tank. A water guide pipe is fixedly connected between the water pump outlet port and heat-absorbing bend I. A return water pipe is fixedly connected between heat-absorbing bend II and the cold water tank.

[0006] As a preferred embodiment of this utility model, a controller is provided on the side of the cabinet, the output terminal of the temperature sensor is electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the input terminals of the air blower and the water pump.

[0007] As a preferred embodiment of this utility model, the cabinet is provided with an equipment partition, and the surface of the equipment partition is provided with a number of ventilation openings spaced apart.

[0008] As a preferred embodiment of this utility model, a first dustproof net is provided on the inner side of both the left and right air outlets, and a second dustproof net is provided on the upper end of the air guide shroud.

[0009] As a preferred embodiment of this utility model, the cold water tank is provided with heat dissipation fins, which are symmetrically distributed on both sides of the cold water tank.

[0010] As a preferred embodiment of this utility model, the heat-absorbing bend I, heat-absorbing bend II, U-shaped heat-absorbing tube, heat-absorbing ring, cold water tank and heat dissipation fins are all components made of copper.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a temperature sensor to monitor the internal ambient temperature of the server rack. When the temperature reaches a preset value, the controller activates the air blower and water pump. The air blower directs external airflow into the rack, allowing heat to escape through the left and right air outlets. Heat-absorbing bends I and II, a U-shaped heat-absorbing pipe, and several heat-absorbing rings absorb the heat generated by the electrical equipment inside the rack. The water pump draws cold water from the cold water tank through a pumping and guiding pipe. The cold water passing through heat-absorbing bends I, U-shaped heat-absorbing pipes, and heat-absorbing bends II carries away the heat. Simultaneously, the outward-expelled airflow blows towards heat-absorbing bends I and II, rapidly cooling them. This facilitates timely heat removal from the rack, effectively controlling the internal ambient temperature and preventing it from becoming too high, thus reducing the risk of damage to the internal electrical equipment.

Several right air outlets 106 are spaced apart on the right side of the cabinet 1. A heat-absorbing bent pipe 12 is installed inside the cabinet 1 near the right air outlet 106. A heat-absorbing bend II3 is fixedly connected to heat-absorbing bend I2 and heat-absorbing bend II3 by a U-shaped heat-absorbing pipe 4. Several heat-absorbing rings 401 are fixedly sleeved on the outside of the U-shaped heat-absorbing pipe 4 at intervals. A temperature sensor 7 is installed on the inner wall of the cabinet 1. A cold water tank 5 is fixedly installed on the back side of the cabinet 1 by a bracket 107. A water pump 6 is installed on the cold water tank 5. A water pump 601 extending into the cold water tank 5 is fixedly connected to the water inlet port of the water pump 6. A water guide pipe 201 is fixedly connected between the water outlet port of the water pump 6 and heat-absorbing bend I2. A return water pipe 301 is fixedly connected between heat-absorbing bend II3 and cold water tank 5.

[0020] Among them, such as Figure 1 and Figure 2 As shown, a controller 8 is provided on the side of the cabinet 1. The output of the temperature sensor 7 is electrically connected to the input of the controller 8. The output of the controller 8 is electrically connected to the input of the air blower 104 and the water pump 6. The temperature sensor 7 monitors the internal ambient temperature of the cabinet 1. If the temperature reaches the preset value, the controller 8 controls the air blower 104 and the water pump 6 to start running.

[0021] Among them, such as Figure 2 As shown, the cabinet 1 has an internal equipment partition 9, on which electrical equipment can be installed. The surface of the equipment partition 9 is provided with several ventilation openings 901 at intervals, so as to achieve the purpose of good ventilation effect of the equipment partition 9.

[0022] Among them, such as Figure 4 As shown, a first dustproof net 108 is provided on the inner side of both the left air outlet 105 and the right air outlet 106, and a second dustproof net 109 is provided on the upper end of the air guide shroud 103 to prevent external dust and impurities from entering the cabinet 1.

[0025] The working principle of this utility model:

[0026] During operation, the temperature sensor 7 monitors the internal ambient temperature of the cabinet 1. When the temperature reaches the preset value, the controller 8 controls the air blower 104 and water pump 6 to start running. The air blower 104 blows external airflow into the cabinet 1, causing heat to be discharged outward through the left air outlet 105 and the right air outlet 106. The heat generated by the electrical equipment inside the cabinet 1 during operation is absorbed by the heat absorption bend I2, heat absorption bend II3, U-shaped heat absorption pipe 4, and several heat absorption rings 401. The water pump 6 pumps cold water from the cold water tank 5 through the water pump 601 and the water guide pipe 2. The cold water, after being extracted and passing through the heat-absorbing bend I2, U-shaped heat-absorbing pipe 4, and heat-absorbing bend II3, carries away the heat and finally flows back to the cold water tank 5 through the return water pipe 301. At the same time, the airflow discharged outward blows towards the heat-absorbing bend I2 and heat-absorbing bend II3, causing them to cool down quickly. This facilitates the timely discharge of heat from the cabinet 1 and can efficiently control the internal ambient temperature of the cabinet 1. If the temperature is lower than the preset value, the controller 8 will control the air blower 104 and water pump 6 to shut down, which helps to achieve energy saving.
